Graduate What is the heat capacity of water in meta-stable equilibrium?

Click For Summary
The heat capacity of water does vary with temperature, but it remains relatively consistent across different states, including super-heated and super-cooled conditions. Super-heated water above 100°C and super-cooled water below 0°C do not undergo phase transitions, which affects their heat capacity. Specific heat capacity can be tabulated under isobaric (constant pressure) and isochoric (constant volume) conditions. The discussion highlights the need for clarity on which conditions are being referenced when discussing heat capacity. Overall, understanding these nuances is essential for accurate thermal calculations involving water.

What is the heat capacity of water in meta-stable equilibrium?
Dear experts,

I noticed that super-heated water (liquid water with temperature above 100*C) undergoes boiling when pushed outside the meta-stable equilibrium.

I was wondering, is the heat capacity of liquid water above 100*C the same as liquid water with temperature between 0*C and 100*C?

Similarly, for super-cooled liquid water (liquid water with temperature below 0*C), is its heat capacity the same as liquid water with temperature between 0*C and 100*C?

Thank you for your time.ORF

Google gave me literally hundreds of tables and charts. Your answer must vary with temperature, but does not greatly diverge from one.

If these are not what you want, you need to be more specific. Note that if water is superheated or supercooled, it has not undergone a phase transition. By definition.
 

Thread 'Reference frames, center of rotation, etc'

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
